For our lego project we made a house with an automatic garage door. It was not complicated to make. It has a light sensor which senses when the car goes up the driveway and then tells the garage door to open. There are two outdoor lamps. When the garage closes musical notes let the person know the garage door has closed. On the left of the house, there is a glass door. In the middle of the house there are two slanted windows. It took about 45 minutes to build the house.
There is another light sensor inside the house which senses when a person walks through the door. When the alarm goes on, it starts with a low pitch sound then increases to a high pitch.
Below is a picture and the programming.
